Trash Compactor Disc Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional trash compactors face difficulties in removing compacted trash due to friction and pressure forces, requiring heavy-duty liners and increasing costs and weight as capacity is scaled, and often necessitate manual intervention for emptying.
Innovation Solution
The compactors compact trash into small discs that can be easily removed from a cylindrical compaction bin, reducing frictional forces and allowing for automatic ejection into a separate collection bin, using a compactor mechanism and a collection system that maintains efficiency without enlarging the compactor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the compaction bin is made larger to increase capacity, then the trash compactor can hold more compacted trash, but the weight and cost of the compactor increases
Solution Approach 1:
The system divides the trash handling into two separate bins: a compaction bin for active compaction and a collection bin for storage. This segmentation allows the compaction bin to remain small and lightweight while the collection bin handles the bulk storage capacity, resolving the contradiction between capacity and weight.
Solution Approach 2:
The invention introduces a temporal dimension to capacity management by enabling continuous operation through automatic ejection. Instead of increasing spatial capacity in one dimension, the system maintains a small compaction bin that repeatedly compactes and ejects trash into a separate collection bin, achieving high capacity through repeated cycles rather than large size.
2Quantity of substance
If the compaction bin is made larger to increase capacity, then the trash compactor can hold more compacted trash, but the cost of the compactor increases
Solution Approach 1:
By segmenting the system into a small compaction bin and a separate collection bin, the compaction bin requires less expensive, smaller mechanical equipment. The cost of manufacturing is reduced because the compaction mechanism doesn't need to be scaled up, while the collection bin serves as a simple, low-cost storage container.
Solution Approach 2:
The automatic ejection system allows the compactor to service itself by ejecting compacted trash without manual intervention. This self-service capability eliminates the need for expensive manual emptying mechanisms or large access doors, reducing manufacturing costs while maintaining capacity through continuous operation.
3Ease of manufacture
If conventional trash liners are used in the compaction bin, then the cost is reduced, but the liners tear easily due to extraordinary forces
Solution Approach 1:
The invention extracts the high-stress compaction function from the liner by using a separate compaction bin that doesn't rely on the liner for structural support. The liner in the collection bin only needs to contain stored trash, not withstand compaction forces, allowing conventional inexpensive liners to be used reliably.
Solution Approach 2:
The compaction bin acts as an intermediary that absorbs all the extraordinary forces during compaction. By separating the compaction process from the collection bin, the liner only experiences gentle storage conditions, not the high pressures and friction of active compaction, thereby maintaining durability with standard liners.
4Device complexity
If manual emptying is required, then the system structure is simpler, but continuous operation is interrupted and efficiency is reduced
Solution Approach 1:
The system achieves self-service through automatic ejection mechanism that periodically empties the compaction bin into the collection bin without manual intervention. This maintains relatively simple system structure while enabling continuous operation, as the automatic ejection only requires basic sensors and actuators rather than complex continuous compaction mechanisms.
Solution Approach 2:
Instead of continuous manual emptying or complex continuous operation, the system uses periodic automatic ejection cycles. The compaction bin operates continuously, compacting trash and periodically ejecting it when full, creating an efficient rhythm that maintains high productivity with minimal system complexity.

This solution simplifies the removal of compacted trash, reduces the need for expensive liners, and allows for continuous operation without manual emptying, enhancing efficiency and reducing weight and cost by using a standard-strength liner in the collection bin.
Implementation Method 1
a compactor mechanism operatively coupled with the compaction bin to compact the trash within the compaction bin
Implementation Method 2
